Police are shown at the scene of a shooting in Summit Township that caused nearby Vandercook Lake High School to be locked down.

SUMMIT TWP., MI -- A lockdown at Vandercook Lake High School/Middle School and Townsend Elementary School that police say was related to a nearby shooting has been lifted, said Vandercook Lake Superintendent Tony Hollow.

The schools were locked down for about 50 minutes and the lockdown ended at about 11:15 a.m., Hollow said.

"It was non-school-related," he said of the situation that resulted in what's called a soft lockdown. That means outside doors are locked and secured, but students can move about within the schools, Hollow said.
